Description
Gegenstand der Erfindung ist ein Verfahren zum Entfernen des Schweißbartdrahtes aus Rohren, insbesondere extrem langer aufgewickelter Rohre.The invention relates to a method for removing the welding beard wire from pipes, in particular extremely long coiled tubes.
Bei der Herstellung längsnahtgeschweißter Rohre fällt bekanntlich beim Abschaben des Schweißbartes ein im Innern des Rohres verbleibender Schweißbartdraht an. Dessen Entfernung ist bei bereits auf Länge geschnittenen Rohren einfach. Bisher ungelöst bzw. mit erheblichen Schwierigkeiten verbunden ist jedocn die Beseitigung des Schweißbartdrahtes bei exlrem langen bzw. bereits aufgewickelten Rohren.In the manufacture of longitudinally welded pipes, it is well known that when the weld bit is scraped off, it falls a weld beard wire remaining inside the pipe. Whose distance is already at length cut pipes easy. However, this has not yet been resolved or is associated with considerable difficulties Elimination of the welding beard wire in the case of extremely long or already wound pipes.
Aufgabe der Erfindung ist es, ein Verfahren zu schaffen, mit dem die Entfernung des Schweißbartdrahtes bei extrem langen Rohren, insbesondere bereits aufgewickelten Rohren auf einfache und sichere Weise möglich wird.The object of the invention is to create a method with which the removal of the welding beard wire in extremely long pipes, especially pipes that have already been wound Pipes in a simple and safe way is possible.
ίο Erfindungsgemäß wird zur Lösung dieser Aufgabe das im Kennzeichen des Patentanspruchs Erfaßte vorgeschlagen. Dabei ist die Flüssigkeit z. B. Wasser, und die gesamte Flüssigkeitssäule kann mit hohem Druck, beispielsweise 15 bis 20atü, herausgedrückt werden.ίο According to the invention is used to solve this problem proposed what is covered in the characterizing part of the claim. The liquid is z. B. water, and the entire column of liquid can be pushed out at high pressure, for example 15 to 20 atmospheres.
Durch diese Maßnahme wird der Schweißbartdraht von der inkompressiblen Flüssigkeitssäule mitgenommen
und gleitet mit der gleichen Geschwindigkeit wie die Flüssigkeit aus dem Rohrende heraus.
Es ist auch möglich, der Füllflüssigkeit kleine Kunststoffstücke zuzusetzen bzw. unmittelbar nach dem Abtrennen
des Schweißbartes den entstehenden Draht mit Kunststoffmasse einzuschäumen. Nach Auffüllen der
gesamten Rohrlänge mit Füllflüssigkeit wird, wie vorstehend beschrieben, der gesamte Inhalt, d. h. Draht,
Kunststoff und Füllflüssigkeit herausgedrückt. Die verwendeten Kunststoffstücke sind wieder einsetzbar.As a result of this measure, the welding beard wire is carried along by the incompressible column of liquid and slides out of the pipe end at the same speed as the liquid.
It is also possible to add small pieces of plastic to the filling liquid or to foam the resulting wire with plastic compound immediately after the welding bit has been cut off. After the entire length of the pipe has been filled with filling liquid, the entire contents, ie wire, plastic and filling liquid, are pressed out as described above. The plastic pieces used can be reused.
Mit dem erfindungsgemäßen Verfahren wird die Herstellung von geschweißten Rohren unbegrenzter Länge in verkaufsfertigem Zustand möglich, da die Beseitigung des Schweißbartdrahtes durch keine Länge begrenzt wird.With the method according to the invention, the manufacture of welded pipes becomes more unlimited Length possible in the ready-for-sale condition, as the welding beard wire is not eliminated by any length is limited.
